WebDec 12, 2016 · Polymers are processed into films and other useful shapes through liquid → solid transitions. The structure that forms is always non-equilibrium and the processing parameter space is typically vast. We develop measurements to characterize the structure that forms during polymer processing, and to characterize how that structure forms. WebFeb 19, 2024 · The overall effect of the draw-down process is increased polymer chain density and strength. Therefore, drawn fiber usually possesses superior and often preferable mechanical attributes in comparison to simple extruded monofilament. Stretching or drawing down of the extruded monofilament is a process (Fig. 2).

WebPolymer processing aids are typically used to reduce melt fracture of polymers, especially linear polyethylene. Melt fracture is a type of flow instability that begins as a roughening of the surface (shark skin) and at higher output can lead to severe distortion of the polymer.
